如何使用具有Java配置的CommandLineJobRunner启动Spring Batch Job [英] how to launch Spring Batch Job using CommandLineJobRunner having Java configuration

问题描述

我在基于Java的配置文件中有批处理作业定义.我已经看到 CommandLineJobRunner 可用于启动作业，但是作业定义应在.xml中定义.我想使用 CommandLineJobRunner 来运行基于Java的配置中定义的作业.

I have my batch job definition in Java based configuration file. I have seen that CommandLineJobRunner can be used to launch job, but the job definition should be defined in .xml. I want to use CommandLineJobRunner to run my jobs defined in java based configuration.

根据此处的文档: https://docs.spring.io/spring-batch/trunk/reference/html/configureJob.html#commandLineJobRunner ，没有详细说明.

According to the documentation here: https://docs.spring.io/spring-batch/trunk/reference/html/configureJob.html#commandLineJobRunner, there is no details to do so.

我们还能做到吗?还有什么其他选择?

Can we even do this? What can be the other alternatives?

推荐答案

CommandLineJobRunner 的第一个参数可以是:

The first argument of CommandLineJobRunner can be either:

• 包含作业定义的xml文件
• 或包含作业定义的配置类的标准名称

从Spring Batch v4开始，每个文档页面的顶部都有一个切换开关，可让您显示Java或Xml配置中的示例.例如，当切换开关设置为"Java"时，此处的文档部分:

Starting from Spring Batch v4, there is a toggle on the top of each documentation page that allows you to show examples in Java or Xml config. For example, when the toggle is set to "Java", the documentation section here: https://docs.spring.io/spring-batch/4.0.x/reference/html/job.html#runningJobsFromCommandLine shows how to use the CommandLineJobRunner with a Java configuration class:

$>java -cp your/class/path org.springframework.batch.core.launch.support.CommandLineJobRunner io.spring.EndOfDayJobConfiguration endOfDay schedule.date(date)=2007/05/05

io.spring.EndOfDayJobConfiguration 是包含 endOfDay 作业定义的完全限定的类名.

io.spring.EndOfDayJobConfiguration is the fully qualified class name containing the endOfDay job definition.
